Access "Do RAID levels still matter?"
This article is part of the Vol. 6 No. 9 November 2007 issue of RAID turns 20: Do you still need it?
Most new arrays stripe data across their spindles automatically to increase performance and better use disk capacity. With capabilities like that, RAID could become a thing of the past. The 20-year anniversary of the invention of RAID by David Patterson, Garth Gibson and Randy Katz of the University of California at Berkeley is less than a year away. Their revolutionary paper, A Case for Redundant Arrays of Inexpensive Disks (RAID), changed the way server-class computers stored data. Soon after RAID burst upon the scene, storage administrators had to wrestle with the pivotal RAID question: "How shall I place data on my hard disks to optimize capacity, performance and data protection?" But that question is becoming less relevant because most new storage arrays automatically distribute data onto a number of spindles, which eliminates the manual task of selecting RAID levels. Most Storage readers don't require an introduction to the concepts of RAID. But the rules of the game are changing. As recently as five years ago, storage administrators were constantly ...

Where encryption fits best
by Jerome M. Wendt and Joshua Konkle
Everybody knows they should encrypt tapes that go offsite, but many are still on the fence about where encryption should occur in their storage environments. There are a number of options, ranging from using your backup app's encryption capabilities to installing a purpose-built encryption appliance. We weigh the pros and cons of the available alternatives so that you can decide which approach best suits your shop.
